Answer:
The molarity is: 1 M
Explanation:
We define molarity as an amount of moles in 1000ml of solution (1 liter)
500ml---------0,5 moles AlCl3
1000ml------x= (1000ml x 0,5 moles AlCl3)/500ml = 1 moles ACl3--> 1 M
Explanation:
Strength of intermolecular forces depends on the number of carbon atoms present in a compound. More is the number of carbon atoms attached linearly to each other more will be the surface area occupied by it. Hence, more is the strength of the compound.
This means that more is the branching present in a compound or lesser is the number of carbon atoms present in it then less will be the strength of intermolecular forces in the compound.
Thus, we can conclude that given compounds are placed in order of decreasing strength of intermolecular forces as follows.

Answer:
<h2>Density = 0.8 g/cm³</h2>
Explanation:
The density of an object can be found using the formula
<h3>
![Density(\rho) = \frac{mass}{volume}](https://tex.z-dn.net/?f=Density%28%5Crho%29%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20)
</h3>
From the question
mass of kerosene = 36.4 g
volume of kerosene = 45.6 mL
To find the density substitute the values into the above formula and solve
We have
<h3>
![Density = \frac{36.4}{45.6}](https://tex.z-dn.net/?f=Density%20%3D%20%20%5Cfrac%7B36.4%7D%7B45.6%7D%20)
</h3>
= 0.7982
We have the final answer as
<h3>Density = 0.8 g/cm³</h3>
Hope this helps you
Atoms of the same element but with different atomic masses are called isotopes. They possess a different atomic mass, due to the indifferent number of neutrons that the atoms of a given element have.
Answer:
13.8889 m/s
Explanation:
speed= distance / time
speed answer must be in m/s
so convert 300km in to m
multiply 300km by 1000 to get 300000m
time must be in seconds so multiply 6 hours by 3600 to get 21600s
so 300000m/21600s = 13.8889 m/s
